think-interval-calibration-check — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited think-interval-calibration-check (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

People state uncertainty as intervals - "two to four weeks, 90 percent sure" - and those intervals are reliably too narrow. Overprecision is the most robust form of overconfidence: stated 90 percent intervals contain the true value far less than 90 percent of the time, and subjective intervals are sometimes only a fraction as wide as the judge's own information would warrant. A stated "90" that historically hits 50 is not a confidence level, it is a habit of speech, and everything downstream that takes the number literally - an expected-value calculation, a risk model, a commitment - inherits the error. This method interrogates the WIDTH of a stated uncertainty: does your 90 mean 90? It runs two coupled moves that both operate on the width and never on the location of the estimate - an equivalent-bet indifference test at elicitation time, and hit-rate scoring against resolved outcomes - and emits a calibration scorecard. The durable move is not asking "how sure are you?" again. It is converting that question into a concrete bet, widening until the bet is genuinely a toss-up, and scoring the stated confidence against the truths that actually arrive.
think-reference-class-forecasting (anchor on the base rate of comparable cases) or think-fermi-estimation (build the number from factors). Wrong number, use those; untrustworthy "sure," use this.consider-the-unknowns move) and never generates a second estimate to average (that is think-dialectical-bootstrapping). It is content-blind: it only asks whether the stated number means what it claims.When asked to pressure-test a stated confidence interval or audit whether a "90 percent sure" is worth its face value, follow these steps:
think-reference-class-forecasting or think-fermi-estimation and stop. This method resizes the stated uncertainty; it never relocates the estimate.references/TEMPLATE.md: each interval, its nominal confidence, the bet verdict, the adjusted interval, and the hit rate and over/underprecision diagnosis where a track record exists - with the pre-printed evidence caveat carried into the artifact.Use the template in references/TEMPLATE.md. The deliverable is the filled calibration scorecard - the focal claims, each stated interval with its nominal confidence, the equivalent-bet verdict, the adjusted interval at indifference, and the hit-rate-versus-nominal diagnosis wherever outcomes resolve - not a prose essay. The evidence caveat ships inside the artifact by construction. Never present the agent's own confidence as a calibrated reading, and never report the central estimate as corrected (this method resizes width, it does not relocate the number).
Before finalizing, verify:
evidence/dossier.md).Tier P (governing; preliminary M overturned to P). The underlying phenomenon - interval overprecision - is established at strong-research level: 98 percent intervals cover roughly 60 percent of true values (Alpert and Raiffa, 1982), and 90 percent intervals contain the truth less than 45 percent of the time (Soll and Klayman, 2004). Scored feedback is among the few interventions with controlled evidence of improving calibration (Lichtenstein, Fischhoff and Phillips, 1982). But a robust bias is not evidence the specific fix works. The M-flavored training results sit on siblings, not this protocol: Lichtenstein and Fischhoff (1980) trained two-alternative half-range items with modest-to-nil transfer, and Klayman et al. (1999) show calibration is not unitary across formats, blocking that transfer; the controlled interval-time remedies tested are fractile decomposition and full-range assignment (Soll and Klayman 2004; Haran, Moore and Morewedge 2010), not the equivalent bet; the strongest training gain (Chang et al., 2016) came from a bundled curriculum; and the equivalent-bet device itself has zero controlled outcome evidence - only interview doctrine (Spetzler and Stael von Holstein, 1975) and excluded vendor data (Hubbard). Grading M would launder cousins' robustness onto the actual move, so the governing grade is P. All evidence is transferred from human subjects; nothing validates the protocol run by or on an AI agent, and the model cannot calibrate itself (verbalized LLM confidence is overconfident - Xiong et al., 2024). The skill ships as an uncertainty-honesty aid that promises partial correction, never calibrated certainty. Full grading, sources, and caveats: evidence/dossier.md.
